Prison System Crisis 2026: Impact on Criminal Defence in Spain

The Spanish prison system is going through a critical situation in 2026: structural overcrowding, a sharp shortage of officers and growing pressure on prison benefits arising from recent reforms. As lawyers experienced in prison law, we explain the real impact of the crisis and the defence routes to safeguard your rights.

The Prison Situation in 2026

The official figures from the Prison Administration and the reports of the National Mechanism for the Prevention of Torture of the Ombudsman paint a worrying picture:

• Overcrowding in numerous facilities, with modules operating above their operational capacity.
• Shortage of surveillance officers, which translates into restrictions on leave, delays in assessing progressions and a reduction of activities.
• Saturation of the Prison Supervision Sections of the Courts of Instance (Sección de Vigilancia Penitenciaria; formerly the Prison Supervision Courts) (JVP), with extended timescales for resolving complaints, appeals and benefit applications.
• Structural problems in cells, mental health and healthcare coverage, worsened by the ageing of the prison population.

This context directly influences the inmate's daily situation and, above all, their real prospects of progression and release.

Organic Law 1/2025 on Efficiency: Impact on Prison Enforcement

The Organic Law 1/2025 on efficiency measures for the Public Justice Service has introduced relevant changes affecting criminal enforcement and the prison sphere:

• Greater use of videoconferencing in court proceedings (Art. 229.3 LOPJ, as worded by Organic Law 1/2025), which the defence must monitor where inmates are involved so that it does not erode the right to a defence.
• Restorative justice: express regulation, also available to convicted persons and relevant, for instance, when setting the conditions of a suspended sentence, with potential effects on the assessment of the reintegration prognosis.
• New court organisation: the Prison Supervision Sections become Prison Supervision Sections of the Courts of Instance.

Efficiency is desirable, but the defence must ensure that essential safeguards are not sacrificed: physical presence at decisive proceedings, immediacy in the assessment of evidence and the right to a full and effective defence.

Prison Benefits Under Pressure

The three major prison benefits face increasingly strict scrutiny:

Open Regime and Third-Grade Classification

Classification in the third grade (Art. 72 LOGP) currently requires a rigorous assessment of the reintegration prognosis, compliance with civil liability and prison conduct. The saturation of the system delays progressions that objectively meet the requirements. The defence must document family roots, a job offer, stable housing and effective payment of civil liability in order to drive the progression forward.

Parole (Art. 90 CP)

Ordinary parole under Art. 90 CP requires the classic prerequisites: being in the third grade, having served three quarters of the sentence, good conduct and a favourable judicial assessment of the inmate's circumstances. Advanced parole under Art. 90.2 CP, available at two thirds, additionally requires work, cultural or occupational activities, and every modality requires civil liability to have been satisfied under Art. 72.5 and 72.6 LOGP.

Remission and Release on Leave

Although remission of sentences through work was abolished by the 1995 Criminal Code, it still applies to old sentences still being served. Ordinary release on leave (Art. 154 RP) is the most widely used tool to prepare reintegration: it is granted from the quarter-served point, for up to seven days each and up to 36 days per year in second grade or 48 in third grade. A refusal can be appealed before the JVP and, on further appeal, before the body designated by the 5th additional provision LOPJ.

Routes Before the Prison Supervision Section

The Prison Supervision Section is the key piece of the system. The LOGP and the Prison Regulations configure a range of defensive instruments:

• Appeals against classification and regression decisions of the central prison authority and against disciplinary sanctions (Art. 76.2.e and f LOGP).
• Complaints and requests about leave, including extraordinary leave, and about transfers affecting rights (Art. 76.2.g LOGP).
• Complaints about material conditions: health, hygiene, communications, family visits, food.
• Appeals against refusals of parole or third-grade classification.

Against the JVP's decision, an application for review and, where applicable, an appeal are available: before the Provincial Court in prison-regime matters and before the sentencing court in matters of enforcement of the sentence, such as classification or parole (5th additional provision LOPJ). A technical defence specialised in prison enforcement knows the deadlines, the competent courts and the settled case law of each Provincial Court, which multiplies the chances of success.

Dignity, Constitutional Court Doctrine and ECtHR Case Law

The Constitutional Court has consolidated a demanding doctrine on the dignity of the person deprived of liberty: imprisonment is a penalty of deprivation of liberty, not a penalty of degradation. Any additional restriction must be legally provided for, be proportionate and preserve dignity as an intangible core.

The European Court of Human Rights has repeatedly condemned States for breach of Art. 3 ECHR (prohibition of inhuman and degrading treatment) in cases of:

• Severe overcrowding with less than 3 m² per inmate (the ECtHR case law on detention conditions and minimum personal space in prison, Art. 3 ECHR).
• Deficient material conditions of the cell: ventilation, light, hygiene, privacy.
• Lack of adequate medical care, especially in mental health.
• Prolonged isolation without individualised justification.

These standards can be invoked directly within the domestic legal order (Art. 10.2 of the Constitution) and are a powerful tool to challenge prison conditions contrary to dignity.
